Making Solar Panels with a Microwave [video]

  Very impressive, I really liked how low tech it all was (except for buying a high purity Si wafer but I can see why growing a crystal that size wasn't on the agenda). Nice to mention Jeri, that first 'cooking with Jeri' episode probably ranks as the all-time-high for makers in my book.

    I'm semithrilled to learn that TEOS is hotseller on eBay.. (BC intrusive thoughts of inhaling glass)

    Same reaction to purportedly sub-$30/300degC homemade solar cells (BC lead poisoning) inclusive of equipment

    (Somewhat more expensive, though more edible ingredients)

  After refreshing several times to avoid logging in, the gGods decided to let the video play. I never knew that this class of thing existed: https://www.amazon.com/Microwave-Professional-Fusing-Melting...

  Anyway, very cool home project.

    I’m trying to understand how the magnetron doesn’t burn out. I am assuming 100% efficiency for microwave absorption?

      It does, eventually. For this type of project don’t use a microwave that you plan on ever using for food - or anything else - ever again.

    Same! First learned of these maybe one year ago. Need a spare microwave for experiments…
